Use async Functions Instead of Callbacks

Overview

Prefer async/await over callbacks for cleaner code and better type flow.

Callbacks create nested, hard-to-follow code. Promises and async/await flatten the structure, make types flow naturally, and enable better error handling.

When to Use This Skill

• Writing any asynchronous code
• Tempted to use callback-style APIs
• Chaining multiple async operations
• Need to compose concurrent operations
• Working with APIs that return Promises
